我需要修改具有多個名稱空間的xml文檔。我的代碼在本地機器上運行時沒有問題，但是當我將它部署到IBM Websphere應用程序服務器時遇到了java.lang.IncompatibleClassChangeError。評估具有名稱空間的xpath表達式時IncompatibleClassChangeError
我使用的是xercesImpl-2.8.1.jar和xalan-2.7.0.jar。 是什麼導致了這個錯誤，我該如何解決它？或者，是否有其他方法來修改名稱空間支持的XML文檔？
代碼：
System.setProperty("javax.xml.parsers.DocumentBuilderFactory", "org.apache.xerces.jaxp.DocumentBuilderFactoryImpl");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
DocumentBuilder db = dbf.newDocumentBuilder();
org.w3c.dom.Document doc = db.parse(new java.io.FileInputStream("c:/test.xml"));
System.setProperty("javax.xml.xpath.XPathFactory", "org.apache.xpath.jaxp.XPathFactoryImpl");
XPathFactory xf = XPathFactory.newInstance();
XPath xpath = xf.newXPath();
xpath.setNamespaceContext(new MyNamespaceContext());
// get the node for editing
String xpathExpr = ...
org.w3c.dom.Node n = (org.w3c.dom.Node)xpath.compile(xpathExpr).evaluate(doc, XPathConstants.NODE); // IncompatibleClassChangeError here
